SIST EN 50065-2-1:2004/A1:2006 is the Slovenian publication of the CENELEC amendment EN 50065-2-1:2003/A1:2005. It covers immunity requirements and test methods for mains communications equipment and systems (MCES) that use signals from 95 kHz to 148.5 kHz on low-voltage electrical installations. Engineers, test laboratories and buyers use it to check how MCES behave on signal, power and earth ports under conducted, radiated and electrostatic disturbances.

What does SIST EN 50065-2-1:2004/A1:2006 specify?

SIST EN 50065-2-1:2004/A1:2006 applies to equipment that transmits or receives information over low-voltage electrical systems in residential, commercial and light industrial environments. The amendment keeps the focus on EMC immunity for MCES and on tests that are done port by port.

The standard is organized into a foreword, Clause 1 on scope, Clause 2 on normative references, Clause 3 on definitions, Clause 7 on immunity specifications, and Annex A as a normative test circuit.

Annex	What it covers
Annex A	Test circuit for the conducted-interference arrangement and the use of Port A

The scope also makes clear what sits outside the document. It does not cover immunity between mains communication systems operating in the same band, immunity to signals from Power Line Carrier systems on high- or medium-voltage networks, or safety matters.

What are the key requirements of SIST EN 50065-2-1:2004/A1:2006?

SIST EN 50065-2-1:2004/A1:2006 sets immunity tests by port and by disturbance type. In practice, this means the test plan must match the actual interface on the equipment, not just the product as a whole.

Port-based immunity testing

Clause 7.2.1 ties the immunity requirements to the ports under test, and the amendment adds a reference to Table 6 of 7.2.2. For manufacturers and test labs, this means the test report has to show which port and which disturbance arrangement were used.

Signal, control and power ports

Table 2 is clarified for low-level signal ports, especially where the signal port and the AC power port are different. That matters when equipment has separate communication and mains interfaces, because the right table depends on how the ports are built.

Table 3 covers d.c. input and output power ports, including surge testing at ± 0.5 kV for common mode and differential mode. Table 4 covers a.c. input and output power ports, with voltage interruptions extended to 5 s and surge values set at ± 2 kV common mode and ± 1 kV differential mode. These settings tell the tester what stress the equipment must tolerate on its power connections.

Earth port requirements

The amendment adds Table 5 for the earth port, described as the functional ground terminal. It includes radio-frequency immunity from 0.15 MHz to 80 MHz with 3 V, 80 % AM at 1 kHz, and fast transients at ± 0.5 kV using the capacitive clamp. The table also assigns performance criteria A and B, so acceptance is not the same for every test.

Narrow-band conducted interference

Clause 7.2.2 is revised so that the coupling network is disconnected from the measurement network and connected to Port A as shown in Annex A. In practice, this defines how the disturbing signal is applied to the EUT and reduces ambiguity in the conducted-interference setup.

Test circuit use

Annex A links Port A to the tests listed in Table 4 and Table 5. That helps laboratories build the correct circuit before running type tests or compliance measurements.

What terms does SIST EN 50065-2-1:2004/A1:2006 define?

• MCES - mains communications equipment and systems that transmit or receive information on low-voltage electrical installations.
• Low-voltage electrical installations - the electrical networks on which the equipment uses the 95 kHz to 148.5 kHz signalling range.
• d.c. - direct-current power ports, covered separately from a.c. ports.
• a.c. - alternating-current power ports, with their own interruption and surge requirements.
• Functional ground terminal - the earth port covered in Table 5.
• EUT - the equipment under test in the specified test circuit.
• Port A - the port used in Annex A to apply the disturbing signal in the conducted-interference arrangement.
• Performance criterion A / B - the acceptance classes assigned to the tests in the immunity tables.

Who uses SIST EN 50065-2-1:2004/A1:2006?

SIST EN 50065-2-1:2004/A1:2006 is used by manufacturers of mains communications equipment, EMC test laboratories, and design teams working on home and building electronic systems. It is also relevant to quality managers, certification bodies and buyers who need to check immunity performance for products intended for residential, commercial and light industrial environments.

What changed in SIST EN 50065-2-1:2004/A1:2006 from the previous edition?

SIST EN 50065-2-1:2004/A1:2006 is an amendment to EN 50065-2-1:2003 and is identical to EN 50065-2-1:2003/A1:2005. The amendment states these changes:

• updates the normative references, including EN 50082-1 to EN 61000-6-1
• replaces EN 50065-1:1991 with EN 50065-1
• removes “1999” from CISPR 16-1
• adds a reference to Table 6 in Clause 7.2.1
• adds a footnote to Table 2 for low-level signal ports and the relation between signal and AC power ports
• changes the surge values in Table 3 for d.c. ports to ± 0.5 kV
• changes Table 4 for a.c. ports, including a 5 s interruption and new surge levels
• adds Table 5 for the earth port
• revises the conducted-interference connection method in Clause 7.2.2
• updates Annex A and the use of Port A in the test circuit

Which standards are used with SIST EN 50065-2-1:2004/A1:2006?

• EN 50065-1 - gives the frequency-band framework used when the standard refers to different MCES bands.
• EN 61000-6-1 - the general immunity standard named in the updated normative references.
• CISPR 16-1 - referenced in the amendment, with the year designation removed.
• EN 61000-4-6 - provides the conducted RF immunity test method used for the earth port test.
• EN 61000-4-4 - provides the fast transient test method used for the earth port test.

What does the SIST EN 50065-2-1:2004/A1:2006 document contain?

This amendment contains revised immunity tables for signal/control ports, d.c. ports, a.c. ports and the earth port, plus a clarified conducted-interference test arrangement. It also includes a normative test circuit in Annex A and a figure showing how the coupling network and Port A are used.

For practical work, the document is used to set up type tests, prepare compliance reports, and compare equipment against the specified immunity levels and performance criteria.
